The legs 2o face and spaced equally -from the aforesaid cenengage the seats 4 midway between the top and ter plane. The curved portion is provided with bottom of the open face of the box so that the a. fiat seat 5 on its outer face centrally disposed spring pressure is exerted centrally of the open of the open face. face and the lid is pressed evenly at all sides A hood 6 is connected to the box by a pin I against the box. The spring isl proportioned so disposed in the orliice of the lug 2. Pin 'l has 60 that it exerts substantially the same pressure on 3 the lid and lug. The upper edge of the lid is in close proximity with the hood shoulders 24 not in engagementwith the box.

The structure shown-in Figs. 6 to 9 differs from the structure of Fig. 1 mainly in that the spring l preventing the lid turning about the bolt i6 when legs terminate in curved portions 25 disposed Y in curved recesses 26 formed in the lid, the recesses being situated similarly to the seats 4 and While the hoodv Aif desired. A rivet i6 is shown instead of the bolt I6 but the bolt may be sired.

A bail and socket connection is shown in Fig. 10 which may be employed in either of the structures of Fig. 1 or Fig. 6. It eliminates the bolt and rivet, which may become loose from service, and substitutes therefor a pressed steel member having `a ball part l5" anda ,stem part I6" welded in a hole 21 in the lid.

The structure shown in Fig. 11 differs from the structure of Figs. 6 to 9 in that the recesses 26 are eliminated, the curved ends 25"' of the spring legs engaging a at portion of the lid.

The structure shown in Fig. 12 diiers from the structure of.,Figs. 1 to 5 in that the socket l4" is formed 'in the lid 3"" and the rivet I6" is secured to a iiatportion of the hood 6".

The curved portions in their recesses 26 (Figs. 6 to 10) prevent the lid from turning about the axis of the universal joint when the lid is not in engagement with the box.

The hoods of the various embodiments (Figs. 1, 6, 10, 1l and 12) have, respectively, side walls '28, 28', 28", 28' and 28" which have their rear edges in close proximity to the lid. In the case of the embodiment of Figs. 1 to 5 a portion of each of the side walls 28 is in close proximity to the outer side of the adjacent seat 4, this providing another means for preventing the lid 3 from turning about the axis of the bolt I6 of the universal joint when the lid is not in engagement with the box.

When 'the lid of each of the various embodiments is swung open it maintains engagement at its upper edge with the box until it engages the lower edge of the hood. lIhe hood and lid are then swung bodily. Conversely, when the lid is swung closed, its upper portion first engages the hood side wall rear edges and then the lid and hood are swung bodily.

Other parts of the structures of Fig. 6, Fig. 10, Fig. 11 and Fig. 12 corresponding to like parts employed if deofthe structure of Fig. 1 are designated by like reference numerals, with, respectively, one, two, three or four accents added.

The side walls 28 of the embodiment of Fig. 1 are provided with aligned holes 29, and the side walls of the hoods of the other embodiments are similarly provided with these holes. These holes are for use in attaching and detaching the hinge pin to and from the box. To this end a bar is passed through the holes behind the legs of the yoke 2,2 of the spring, the spring being tightened slightly to permit this, which is accomplished according to usual practice.

Types kof pin retainers cther than that shown in Figs. 1 to 4 and involving the same principle are contemplated within the scope ofthe present be merely bent at a right angle over the rear oi?` i the pin end or over the pin shoulder as the case may be, or may be oilset as shown in Figs. 1 to 4 but without forming the slit. Furthermore such types of retainers may be employed at only one end of the pin, permitting the pin to be withdrawn through this side of the hood. In such instances the end of the pin at the opposite side of the hood may be straight or shouldered as required, and at this opposite side the orifice in the hood need not be elongated and any suitable re-y tainer may be used at this opposite side. As an example, a suitable retainer at this Opposite side would be provided by permanently bending an` extended portion of the adjacent eye so that it will be disposed over the end of the pin. The pin would be withdrawn through the elongated orifice side of the hood, and to accomplish this the hood at this side would be manipulated so that the retainer at this side would clear the pin in vthe manner previously stated.

While there have been hereinbefore described approved embodiments of this invention it will as fall within the scope of the appended claim are contemplated as a part of this invention.

The invention claimed and desired to be secured by Letters Patent is:

A closure for an open-faced journal box having a cam hinge lug adjacent the upper margin thereof, comprising a hood having a centrally apertured spherical recess struck inwardly out of the plane thereof; a centrally apertured spherical washer movably disposed in said recess; a pintle hinging said h'ood to said lug; an eyeless closure lid closing the open face of said journal box and having an aperture at the center of said open face and an arcuate ridge struck outwardly out of the plane of said iid at opposite sides of said aperture, said apertures in said lid, recess and washer being in alignment; means extending through said apertures connecting said lid to said spherical washer for limited universal move- Ament of said lid relative to said hood and journal box; and a. torsion spring operatively disposed between said hood and lid, presenting two spaced legs of circular cross section having point contact on said arcuate ridges with the axes of said legs perpendicular to the axis of said ridges, said legs terminating in two spaced coils in contact with said hood and said coils terminating in a loop engaging said cam lug whereby said spring exerts pressure on said hood and lid in all positions of movement relative to said journal box.
